Time out issue with thin-client browser

I am hoping someone may point me in the right direction=2E We are currently having a time-out issue here in the U=2ES=2E A user can be working in a screen and Matrix will kill their session after 30 minutes, losing all their data they entered=2E Even if they are actively working within that 30 minutes=2E This only happens in thin-client and only in the U=2ES=2E, Europe says they do not have this issue=2E Any help will be appreciated=2E

<P>Hi Mike,</P>
<P>Before going into any solution, I would like to ask whether the US and Europe clients have the same common Matrix and Oracle servers?</P>
